Rework Hours with vehicles requiring rework of 63 items: a worked example

Push vehicles requiring rework up to 63 items and the picture changes. This example computes every intermediate figure at that operating point. Use it to budget rework labor and schedule the crew in Commercial Vehicle, Bus & Coach Manufacturing.

The inputs for this scenario

  • Vehicles requiring rework: 63 items (raised for this scenario; the documented default is 25)
  • Hours per rework job: 2 hr (unchanged)
  • Rework technicians on crew: 4 people (unchanged)

Working through the calculation

  • Applying the documented formula (Total labor hours = work items × hours per item) to the inputs above produces each figure below.
  • At this operating point the engine returns 126 hr for total labor hours, the number this scenario is built around.
  • At this operating point the engine returns 31.5 hr for duration with crew.
  • At this operating point the engine returns 63 items for work items.
  • At this operating point the engine returns 2 hr / item for hours per item.

How this compares with the baseline

  • Against the tool's baseline example, where vehicles requiring rework sits at 25 items and the headline result is 50 hr, this scenario comes in 152% above the baseline at 126 hr.
  • It multiplies the number of vehicles needing rework by the hours each job takes to get total labour hours, then divides by crew size to get the wall-clock duration. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total labor hours: 126 hr (headline result)
